Taxonomy:

Citation: Tisochrysis Bendif & Probert, in Bendif et al. 2013

Rank: Genus

Type species: Tisochrysis lute Bendif & Probert, in Bendif et al. 2013

Taxonomic discussion: The genus was created in order to avoid making Isochrysis a paraphyletic genus.

Distinguishing features:
Parent taxon (Isochrysidaceae): Non-calcifying Isochrysidales
This taxon: Similar to Isochrysis, but plastids orange rather than brown.

Original description: Cells solitary, motile, covered by several layers of scales with ten radiating ribs arranged in each of four quadrants. Flagella two, equal, inserted apically with abbre- viated haptonema between, bearing small round scales with 12 radial ridges. Plastid single, parietal, yellow-brown with immersed pyrenoid. Asexual reproduction by division in motile and non-motile stages. Nucleotide sequences of nuclear SSU and LSU rDNA and cox1 gene are distinctive from previously described isochrysidalean taxa.
